Kathryn Hahn has put a spell on the Marvel Cinematic Universe again. The celebrated actress earned an Emmy nomination and her own earworm signature song for her MCU debut as Agatha Harkness in "WandaVision" in 2021.

"WandaVision" aired in 2021 and most of the characters, including Agatha, have not been seen or mentioned in the MCU for years.

"Agatha All Along" premieres Wednesday on Disney+. Here's a "WandaVision" recap (and some other crucial MCU details to remember) before watching.

Episode 1, titled "Sekeest Thou the Road," was written and directed by Jac Schaeffer. Meanwhile, Episode 2, titled "Circle Sewn with Fate / Unlock Thy Hidden Gate," was written by Laura Donney and directed by Jac Shaeffer.

In a strange turn of events, their next witch, a blood witch, is hiding out in a Hot Topic. They’re after Ali Ahn’s Alice Wu-Gulliver, daughter of the powerful witch Lorna Wu, who is rumored to have been lost on the Witches Road.

Marvel Studios’ latest Disney Plus streaming series, Agatha All Along, came out of the gate strong in its two-episode debut. Picking up three years after the events of WandaVision, “Seekest Thou The Road” finds a still bewitched Agatha starring in an episode of a True Detective-esque murder mystery.
